It should just be 2x-5= 125
Then add 5 to both sides
2x= 130
Divide by 2
X= 65

Answer:
A reflection in the x-axis.
Step-by-step explanation:
The first graph passes through the point (0,1) and (1,3).
The second graph passes through (0,-1) and (1,-3).
We can observe that the y-coordinates of the first graph were negated to obtain the second graph.
That is;
This is the mapping for the reflection in the x-axis.
Answer:
Probabilty= 7.66*10^-3
Step-by-step explanation:
A box contains 65 balls numbered from 1 to 65.
9 balls are drawn with replacement.
Probabilty of selecting a number = 1/65
Probabilty of selecting a number
= 0.0154
Probabilty of at least 2 numbers out of 9 selected to have Same number
Probabilty= 9C2(0.0154)^2(0.9846)^7
Probabilty= 7.66*10^-3
